Er - Sorry About That

I wrote in November about an upright citizen who suffered from heavy-handed policing at the Eurostar terminus and was unwise enough to accept a caution. The Police have now apologised and wiped off the caution (how?). That's as it should be, but how likely is is that someone without the Brigadier's impeccable character, and without his ability to get a letter in The Times, would receive anything other than a brush-off?
